1 Claim.

This invention is an improved type of pad or pervious and absorbent containing medium providing means whereby an evaporable or-volatile medication or odorous compound or material may be contained therein.

A further object of this invention is to provide a means whereby the odoriferous material contained in said pad, bandage or the like may be insulated from contact with the air when such material is not needed or when the pads and the like are not in use or in storage, as for instance, in the stocks of merchandisers. A still further object of the invention is the provision of a pad, bandage, or article of similar use, pervious to the air, and containing therein a volatile substance, either medical or odoriferous, or both, and wherein the amount of such medical or odoriferous material allowed to-escape into the surrounding pervious material may be con trolled at the option of the user. I e

A still further object of this invention is the provision of an article of the class described above, in which the part containing the medical or odoriferous material may act as a self-regulating or self-sealing container body.

A further important object of the invention is the provision of an absorbent container, pervious to air which contains a disc lozenge or capsule.

containing or composed of an odoriferous com- 0 pound or material, and additionally, in which the container may carry a supply of face or talcum powder, so that the pad and the disc, lozenge or capsule and power contained therein will function together as a powder puff and sachet.

A still further important object is the provision of a pervious container having controllable medical, antiseptic or odoriferous properties for use as a bandage, sanitary pad or the like.

Other and further objects will be apparent from the following detailed specification which follows.

On the drawings:

Fig. 1 is a plan view of one form of the invention, this type of particular use as a powder pull or sachet, the disc or capsule containing the odoriferous material being indicated by dotted lines.

Fig. 2 is a cross-sectional view of the type of device shown in Fig. 1, taken-on the line 2-2 of Fig. 1.

Fig. 3 is a cross sectional view on the line -33 n of Fig. 4 showing a modified form of the invention, this type of particular application as a bandage, padding or sanitary pad. In this view,

for the sake of clarity, the edges of the outer mesh wrapping which normally enfolds the longitudi- 55 nally extending inner absorbent material are shown turned back from the body of the bandage or the like.

Fig. 4 is a plan view of the modified form of the invention set forth in the preceding paragraph, part of the outer gauze wrapping and part 5 of the upper layer of absorbent material being broken away to show the position, within the pad or containing medium, of the disc, lozenge or capsule containing the medical or odoriferous material, showing also the internal strip which in is impervious to liquids and the like.

Fig. 5 is a perspective view of a modified form of medical or odoriferous material, this being a lozenge or disc of more or less solid medical or odoriferous material, which may be optionally l5 employed to function in the place of the collapsible capsule containing liquid or semi-liquid material.

Fig. 6 is a cross sectional view taken on the line 33 of Fig. 4, showing the relative position of .the disc or the like, shown in Fig. 5, in a puif, bandage or sanitary pad. Y

As shown on the drawings:

The numeral l indicates the hollow capsule or container, as illustrated in preferred form in 25 Figs. 1, 2, 3 and 4. This capsule is preferably made of gelatin, but may also be made of Celluloid, base metal or the like, and is depressible and collapsible. Contained within capsule I and illustrated by numeral la is the medication or 30 v odoriferous material, preferably of a liquid or semi-solid consistency. Until the padis put into use the capsule or container I is entirely closed and the material contained therein is thussealed from contact with the air.

As shown in'Figs. 1 and 2, the-numeral 2 indicates the covering material, which, as shown in these views, may consist of a pair of shaped pieces of material preferably of cloth, chamois, or other similar material pervious to the air. As further 0 shown in Figs. 1 and 2, the pair of shaped pieces may be stitched together, back to back, by means of stitches or selvedge illustrated by the numeral 2a.

If desired, face or talcum powder may be place in the enclosed space behindthe two pieces thus sewed together. The capsule l is not fixedly placed behind the two pieces stitched together and forming the faces of the pad, but is capable of movement within the space between said faces 59 which is defined by the side stitching 2a.

. In the modified form of pad or covering for the capsule l-which is particularly illustrated in Figs. 3, 4 and 6 (Fig. 6' additionally'serving to illustrate the use of the modified form of medical or 5 odoriferous material container), the numeral 3 serves to illustrate a covering material pervious to air and having absorbent qualities. preferably cotton, fiber, cellulose or the like. The said cover- 5 ing may be formed of two pieces, pressed together at the edges or of one integral piece folded back upon itself, either construction providing an internal space 3a in which capsule I or disc I 0 may repose. In preferred form, and as shown in Figs.

3, 4 and 6, a strip or piece of material, illustrated by the numeral 4 which may be impervious or partially impervious to liquids or the like, may be interposed behind the said capsule I, limiting the egress'of medical or odoriferous material to the face of the pad, and likewise preventing excretions absorbed by the opposite face from entirely permeating the entire pad.

A piece of gauze or the like, illustrated by the numeral 5, may be utilized to enclose the opposed faces of pad 3, this gauze extending substantially outward from the portions of pad 3 on either side thereof, as shown in the drawings, and folded back so as to enclose the pad 3, these outward extended edges adapted to be themselves folded 26 back one above the other on the face of said pad,

providing additional absorbent material and effectively holding the pad material 3 in proper position, being for this purpose, the functional equivalent of the stitching shown in Figs. 1 and 2. 30 In the modified form of container for the medication or odoriferous material particularly illustrated in Fig. 5 and further shown in section in Fig. 6 in combination with the modified enveloping cover shown in Figs. 3, 4 and 6, the nedia cation or odoriferous material may be formed into a tablet or disc. A covering Ilia, preferably of gelatin or the like, encloses the said medical or odoriferous material, protecting the same from contact with the air, when the covering Illa is not punctured or broken.

To put the invention into use a pin or other sharp instrument may be passed through the outer covering or padding material, numerals 2 and 3 respectively, and allowed to penetrate the outer shell of the capsule or disc. The capsule, being depressible and containing a liquid, may then be squeezed and a quantity of medication or odorous material will escape onto and be absorbed by the covering or pad material. When a sufflcient quantity has been expelled the capsule has a tendency to seal itself or restrict said opening to such an extent that normal egress of the material is substantially prevented.

To use the modified form of medication or odorous material shown in Fig. 5 the covering Illa may be pierced by passing the point of a pin through the fabric surrounding the disc and passing it a number of times across the face of the disc, scratching and penetrating the cover.

It should be obvious that the shape and size of the capsule! and the disc l0 may be varied in accordance with requirements, and further, that both forms of medication of odorous material may be made available in desired amounts by merely exerting substantial pressure on or twisting and breaking either form of container for the same shown in the drawings.

Various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the advantages of the invention or any features thereof, and nothing herein shall be construed as limitations upon the invention, its concept or structural embodiment as to the whole or any part thereof except as defined in the appended claim.

We claim:

In an article of the described class, the combination of an outer air pervious retaining covering, a plurality of strips of air pervious and absorbent pieces of material placed back to back and forming a pad having an internal space between the face surfaces thereof, a strip of material substantially impervious to liquids and the like interposed in said space, a body having a yieldable and pierceable covering, an odorous or medicinal material in said body, said medicinal or odorous substance being adapted to slowly exude from said body on the material adjacent to the same when the said body is punctured or lacerated.
